CROSS REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. Patent Application Ser. No. 15/949,125, filed Apr. 10, 2018, which claims priority to U.S. provisional application No. 62/620,970, filed Jan. 23, 2018, which are hereby incorporated by reference herein in their entirety.

TECHNICAL FIELD

Embodiments of the invention relate generally to an alert system for analyzing and reporting anomalous internet traffic data and a method of analyzing the data, and more specifically to methods and systems for automatically generating an alert concerning anomalous data.

BACKGROUND

The use of honeypot networks and processors to monitor inbound internet traffic is known. Many of these systems collect data and analyze the data for information about attacks and other anomalous activities.

Existing techniques require manually analyzing data for information about attacks. Though existing techniques may have honeypot networks to study scanning activity, humans must manually mine the resulting data for evidence of an attack. Manual analysis can be time-consuming and inefficient. Furthermore, manual analysis is susceptible to human error. Moreover, manual analysis results in delays, as attacks can only be identified when they are discovered by a researcher. Limited time and resources mean that, in practice, although a signature of an attack may be present and visible in a collected dataset, the signature may only be investigated after the attack has already occurred. In some cases, the signature of the attack may only be investigated sporadically given human resource constraints.

A need exists, therefore, for systems, methods, and devices that overcome this disadvantage.

Embodiments of the invention provide a method and system to identify new cyberattacks as the attacks emerge in real time. Embodiments address a critical need for automating the manual search for signs of attacks. The signs of attacks may include changes occurring in any one of thousands of channels or changes that are difficult or impossible for a human eye to distinguish. Embodiments of the invention monitor attempted connections and corresponding payloads and, when a sign of an attack, such as a change in activity, is detected, embodiments automatically publish alerts.

Embodiments of the invention may automatically detect changes in internet traffic without active user intervention and then, after detecting a change, automatically communicate the detected change to a user. Embodiments of the invention provide a fully automated path from receiving and analyzing internet traffic data to communicating anomalous incidents. Embodiments of the invention focus anomalous behavior of port or payloads. Some embodiments of the invention do not examine the full range of channels to identify anomalous activity.

In embodiments of the invention, a processor is used to monitor and collect data. In other embodiments, set of honeypots continuously monitors indiscriminate scanning behavior on the internet. In embodiments of the invention, collected data may comprise information concerning attempted connections, including port and payload information.

FIG. 1 illustrates a system 100 for analyzing and reporting anomalous internet traffic data, in accordance with embodiments of the present invention. In embodiments of the invention, a processor (not shown) is configured to offer a virtual security appliance 120 and accept a request for a connection to the virtual security appliance 120. In embodiments of the invention, the at least one virtual security appliance 120 is a honeypot. In other embodiments of the invention, there are a plurality of virtual security appliances 120 in communication with each other through, e.g., the Internet 110. As one of ordinary skill would recognize, other embodiments may involve a single processor offering a plurality of virtual security appliances 120.

In normal operation, each virtual security appliance 120 receives connections from various third parties seeking to access the computing resources offered by the virtual security appliance 120. The virtual security appliances 120 collect information regarding these connections for later storage and analysis. In some embodiments, the virtual security appliances 120 are configured to offer honeypot functionality, e.g., presenting services as available on one or more ports and/or emulating the actual functionality offered by these emulated services.

In embodiments of the invention, each virtual security appliance 120 is associated with an individual alert module 160, which may be integrated into the virtual security appliance 120 or otherwise be in communication with the virtual security appliance 120. In other embodiments of the invention, several virtual security appliances 120 ¹, 120 ², 120 ³, 120 ⁴, and 120 ⁵ may be in communication with a single alert module 160. At least one alert module 160 may be configured to analyze the data collected from third-party connections, identify an incident for reporting from the analyzed data and may, in certain embodiments of the invention, be further configured to generate an alert concerning the identified incident.

In certain embodiments of the invention, the generated alert may be a written message, such as a text message, email or pop-up warning, supplied to a user 140 either directly or indirectly. In other embodiments of the invention, a user 140 may be notified about an identified incident with an audio signal.

In certain embodiments of the invention, one or more alert modules 160 are in communication with a hub 130. In embodiments of the invention, the hub 130 receives alerts from at least one alert module 160 at fixed or varying time intervals. For example, in one embodiment of the invention, at least one alert module 160 sends all alerts to the hub 130 once every 24 hours. In other embodiments of the invention, the hub initiates contact with at least one alert module 160 and requests an update from the module 160. In other embodiments of the invention, the hub 130 and alert module(s) 160 interact on an event-driven basis. In certain embodiments, when an alert module 160 detects an anomalous event, the alert module 160 will generate an alert concerning the identified incident and will send that alert to the hub 130. In embodiments of the invention, the hub 130 will provide the received alerts to a user 140 on fixed time intervals. In other embodiments of the invention, the hub 130 will send the alert to a user 140 upon receipt of the alert. In further embodiments of the system, the alert will be automatically sent to a user 140.

In embodiments of the invention, a user 140 can configure the system 100 to send alerts to the user 140 on a schedule or on an event-driven basis. In other embodiments of the invention, a user 140 can adjust the system 100 such that the system 100 may send alerts on a fixed time interval basis at certain times and on an incident basis at other times, or when certain conditions are satisfied. In certain embodiments, the alert may be supplied to a user 140 using a user interface, such as a computer or phone.

In further embodiments of the invention, the alert supplied to a user 140 may include the time at which the identified incident occurred, the source of the third party connection, a record of the data exchanged via the connection, and other relevant information. In embodiments of the invention, the at least one processor may collect attribute data and format the collected data into a plot, table, or chart. In other embodiments of the invention, the at least one processor may format identified incidents into a report, collected into a plot, table, or chart, and may further send the formatted incidents to a user 140.

In embodiments of the invention, a virtual security appliance 120 may be configured to send a message to a user 140 at user-specified time intervals. This message, in certain embodiments, may include all attribute data collected over the user-specified time interval. In other embodiments, the appliance 120 may be further configured to filter the collected attribute data and discard standard, non-anomalous attribute data. In certain embodiments, the appliance 120 may only report anomalous attribute data. In other embodiments, the hub 130 may be configured to filter attribute data collected from all appliances 120 in the system 100.

In some embodiments, attribute data may include metadata about a connection, including but not limited to, the date of the connection, the number of bytes associated with the connection, and source IP. In some embodiments, attribute data may include the content of data sent through a connection.

In certain embodiments of the invention, additional alert modules 160 may be added or deleted from the system 100. These alert modules 160 may be added without interdependencies with other alert modules 160. A user 140 could choose to add an additional alert module 160 to the system 100 while the system is running. In a similar fashion, a user 140 could choose to delete an alert module 160 during the operation of the system 100. For example, in embodiments of the invention, the initial alert modules 160 ¹, 160 ² may be configured to examine anomalies in IP addresses and invalid TCP flags, respectively. If the user 140 determines that an additional alert module 160 ³ is needed to examine anomalies in tunneling activity, the user 140 may add alert module 160 ³ without disabling or otherwise interfering with the system 100 and, specifically, the already existing alert modules 160 ¹ and 160 ². Moreover, if the user 140 determines that the system 100 is producing unnecessary alerts due to a certain alert module 160 ¹, the user 140 may delete the alert module 160 ¹ without interfering with the other existing alert module 160 ². The decision to add necessary alert modules 160 or delete unnecessary alert modules 160 may also be determined by a processor according to a predetermined schedule, the ad hoc satisfaction of one or more criteria specified by rules, or as decided by a machine learning system. In various embodiments, the system 100 can similarly add or delete virtual security appliances 120 without interfering with other virtual security appliances 120.

FIG. 2 is a flowchart of a method to analyze and report anomalous internet traffic data, in accordance with embodiments of the present invention. Embodiments of the method use a processor configured to offer a virtual security appliance. In embodiments, the processor accepts a request for a connection to the virtual security appliance 210. After accepting such a request, the processor is used to collect attribute data 220 about the connection. In certain embodiments, honeypots are used to collect attribute data 220 about the connection. In certain embodiments, at least one alert module may be used to examine at least a subset of the collected attribute data 230 and identify an incident for reporting 240. In other embodiments, independent and modular alert modules may examine different subsets of the collected attribute data 230. In certain embodiments, a processor is used to filter the collected attribute data 230 and discard standard attribute data before identifying an incident for reporting 240.

For example, in certain embodiments, alert modules may be configured to examine anomalies in IP ports, anomalies in IP addresses, invalid TCP flags, tunneling activity, server connection timings, connection duration, size of connection, known exploits, the content associated with a connection, abnormal terminations, and improper handshakes, among other anomalies. In some embodiments, alert modules may be configured to detect anomalous increases in activity during certain time windows. For example, alert modules may be configured to detect increased activity in work-related servers when employees are not expected to be active. In further embodiments, alert modules may be configured to detect anomalous trends in server connection behavior, including detecting sustained constant connections in a channel which previously lacked traffic. In other embodiments of the invention, alert modules may be configured to examine and identify an anomalous connection attribute in the collected attribute data.

In certain embodiments, at least one alert module examines the collected attribute data and identifies an incident for reporting 240. The alert module may continuously examine the collected attribute data to identify incidents for reporting 240 or, in alternate embodiments, the alert module is automatically applied at fixed time intervals. In certain embodiments, multiple alert modules may detect an incident for reporting 240. In embodiments of the invention, including embodiments with multiple alert modules, only one alert module must detect an incident for reporting 250 before proceeding to the next step. In embodiments of the invention, because alert modules are examining different facets of collected attribute data, some facets of data may not register as anomalous.

In certain embodiments of the invention, additional alert modules may be added without interdependencies between other alert modules. For example, in certain embodiments, a user may determine upon receiving the automatically generated alert 250 that the alert modules should be configured to detect anomalies in IP addresses, in addition to detecting invalid TCP flags and anomalies in tunneling activity. A user may then, in certain embodiments, proceed to add an alert module which would be configured to detect incidents for reporting 240 which concerned anomalies in IP addresses. Alerts would then be automatically generated 250 for the three alert modules in accordance with certain embodiments of the invention. This addition of the third alert module would not interfere with the already present alert modules and, in certain embodiments, the three alert modules would operate independently. Furthermore, if a user later decided to delete an alert module after determining the received automatically generated alerts 250 were unnecessary, a user may delete one alert module without interfering with the other existing alert modules. The decision to add necessary alert modules or delete unnecessary alert modules may also be determined by a processor according to a predetermined schedule, the ad hoc satisfaction of one or more criteria specified by rules, or as decided by a machine learning system.

In some embodiments, a user may decide to tune the frequency of an alert module such that the alert module would generate alerts 250 more or less frequently. For example, if a certain alert module should generate alerts 250 twice a day, rather than once every 24 hours, a user may change the frequency of alert generation 250 for a specific alert module. Conversely, in embodiments, if a certain alert module should generate alerts 250 less frequently than other alert modules, a user may alter the frequency of alert generation 250 to reduce the frequency of alerts from the specific alert module.

In some embodiments, all alert modules operate independently with respect to the other alert modules.

In embodiments of the invention, at least one incident for reporting is detected by at least one alert module. The incident for reporting may then be formatted, in accordance with certain embodiments of the invention, such that it may be sent out as an alert to users 250. In embodiments of the invention, information about the incident for reporting may be formatted into plots, tables, or other data representation that a user could use to further analyze the data. In some embodiments, this formatting is automatically created. In other embodiments of the invention, certain alert modules are configured to generate specifically formatted messages when they detect at least one incident for reporting, based on the type and facet of data the alert module examines.

In embodiments, incidents for reporting are translated into notification messages 250 in the form of an automatically generated alert. The message may be sent out to subscribers, in certain embodiments, to notify subscribers about the discovered event. In other embodiments, a subset of individuals responsible for monitoring the detection system may receive a generated alert. In embodiments of the invention, the method step 250 is the first step wherein a human is contacted.

In embodiments of the invention, steps 210-250 are automatic. In some embodiments of the invention, once a notification message is sent out 250 to a subset of users, those users may forward the notification message to additional users or further investigate the notification message. In embodiments of the invention, the notification message may contain only information about ports and payloads which are behaving anomalously. In some embodiments of the invention, such as in the case of a leaderboard artifact, a user may receive an automatically generated message 250 which contains a high-level summary. In other embodiments, a user may receive an automatically generated message 250 which only contains information or data which was determined to be anomalous.

In some embodiments, the notification message is supplied to at least one user using a user interface. In some embodiments, the notification message may include the time at which the incident occurred. In other embodiments, the notification may include the time at which the incident was detected.

In other embodiments of the invention, an alert system for analyzing and reporting anomalous internet traffic data uses a processor to offer a virtual security appliance, accept a request for a connection to the virtual security appliance, and collect attribute data about the connection. In embodiments of the invention, at least one alert module is applied to some of the collected attribute data to identify an incident for reporting and an alert is automatically generated concerning the identified incident. In certain embodiments of the invention, the collected attribute data is filtered and standard attribute data is discarded.

Embodiments of the invention may use a time-series approach alert module. In embodiments using a time-series approach alert module, the alert modules may track connections to particular ports or properties of HTTP payloads. In some embodiments, alert modules may be set manually. In some embodiments, a subset of ports and HTTP payload properties may be manually set with certain user-determined parameters. In some embodiments, these parameters may be adjusted by a user over time. In some embodiments, a user may select a more vulnerable subset of ports to be associated with a specific alert module. In embodiments of the invention, the time when data changes significantly may be flagged by certain alert modules.

Other embodiments of the invention may use a status report alert module. In certain embodiments of the invention, traffic across ports are examined and the number of ports with the largest rise in traffic in a 24-hour period is flagged by the status report alert module. In other embodiments of the invention, this period may be a 6-hour, 12-hour, or 48-hour period. In some embodiments of the invention, the top 5% of ports are flagged. In other embodiments of the invention, the top 1%, 10%, 15%, or 20% of ports are flagged. In other embodiments of the invention, all ports which increase in traffic above a certain predetermined threshold are flagged by the status report alert module. In certain embodiments of the invention, a leaderboard alert regarding the top ports is generated at the end of each set period. This alert is formatted and sent as a notification message 250 to users. In certain embodiments, the alert can serve as a tool for security researchers monitoring periodic incidents of internet traffic on a regular schedule.

In other embodiments of the invention, at least one time-series approach alert modules and at least one status report alert modules are used to collect and monitor attribute data about the connection to the virtual security appliance.

FIG. 3 illustrates a processor 300 configured to analyze and report anomalous internet traffic data. In certain embodiments of the invention, the processor 300 comprises a first persistent computer-readable program code 310 that, when executed by the processor 300, causes the processor 300 to accept a request for a connection to the virtual security appliance. In further embodiments, the processor 300 also comprises a second persistent computer-readable program code 320 that, when executed by the processor 300, causes the processor 300 to collect attribute data about the connection established by the first persistent computer-readable program code 310.

In other embodiments, the processor 300 further comprises a third persistent computer-readable program code 330 that, when executed by the processor 300, causes the processor 300 to apply at least one alert module to at least some of the attribute data set to identify an incident for reporting. In further embodiments, the processor 300 also comprises a fourth persistent computer-readable program code 340 that, when executed by the processor 300, causes the processor 300 to automatically generate an alert concerning the identified incident. In certain embodiments of the invention, once the alert is automatically generated, the alert is reported.

In other embodiments, the processor 300 may also comprise a fifth persistent computer-readable program code 350 that, when executed by the processor 300, causes the processor 300 to supply the alert to a user using a user interface. In embodiments of the invention, the processor 300 may supply the alert to a user on a time interval basis or on an incident basis. In other embodiments, the user may specify if the processor 300 will supply the alert to the user on a time interval basis or on an incident basis.

In certain embodiments, the processor 300 may be configured to format the alert in a chart, plot, or table before the fifth persistent computer-readable program code 350 sends the alert to the user. In further embodiments, the alert sent to a user may also include a time-stamp to indicate to the user when the identified incident occurred.

In embodiments of the invention, the processor 300 may execute the first persistent computer-readable program code 310 to cause the processor 300 to accept a request for a connection to a virtual security appliance. In embodiments of the invention, the first persistent computer-readable program code 310 causes the processor 300 to accept a request for a connection to a honeypot. In embodiments of the invention, the first persistent computer-readable code 310 causes the processor 300 to accept a plurality of requests for connections to a plurality of virtual security appliances.

In embodiments, the processor 300 may, after executing the first persistent computer-readable program code 310, execute a second persistent computer-readable program code 320 to collect attribute data about the connection received by the first persistent computer-readable program code 310. This attribute data may be analyzed by the processor 300 or stored for later analysis.

In embodiments of the invention, each virtual security appliance executing on the processor 300 and receiving connections via the first persistent computer-readable program code 310 is associated with at least one alert module implemented by the third persistent computer-readable program code 330. In embodiments of the invention, the third persistent computer-readable program code 330 may implement a single alert module on a plurality of virtual security appliances. In further embodiments, the third persistent computer-readable program code 330 may be further configured to analyze the data collected from the connections received by the first persistent computer-readable code 310.

In further embodiments of the invention, an alert module associated with the third persistent computer-readable program code 330 may identify an incident for reporting from the collected data. In other embodiments, after the incident for reporting is identified, the processor 300 may execute a fourth persistent computer-readable program code 340 which causes the processor 300 to automatically generate an alert concerning the identified incident. In embodiments of the invention, the fourth persistent computer-readable program code 340 may format the collected data regarding the identified incident into a plot, table, or chart.

In certain embodiments of the invention, the generated alert may be a written message, such as a text message, email, or pop-up warning. In embodiments of the invention, the generated alert may include the time at which the identified incident occurred, the source of the third party connection, a record of the data exchanged via the connection, and other relevant information. In further embodiments, a fifth persistent computer-readable program code 350 may send the generated alert to a user or another computer or security system. In other embodiments, the fifth persistent computer-readable program code 350 may notify a user about an identified incident with an audio signal. In further embodiments, the fifth persistent computer-readable program code 350 may send an alert to a user using a user interface, such as a computer or a phone.

In certain embodiments, the fifth persistent computer-readable program code 350 may send a report containing generated alerts to a user at fixed or varying time intervals. For example, in one embodiment of the invention, the fifth persistent computer-readable program code 350 may send alerts to the user once every 24 hours. In other embodiments, a user may request an update from the processor 300. In other embodiments, the fifth computer-readable program code 350 may send alerts to the user on an event-driven basis. In certain embodiments, when the third persistent computer-readable program code 330 identifies an incident for reporting and the fourth persistent computer-readable program code 340 causes the processor 300 to automatically generate an alert, the fifth persistent computer-readable program code 350 will send the alert to the user.

In further embodiments, the fifth persistent computer-readable program code 350 will send a message to a user at user-specified time intervals. This message, in accordance with certain embodiments, may include all attribute data collected over the user-specified time interval. In other embodiments, persistent computer-readable program code (not shown) may filter the collected attribute data and discard standard, non-anomalous attribute data. In certain embodiments, persistent computer-readable program code 350 may only report anomalous attribute data. In other embodiments, the processor 300 may execute persistent computer-readable program code to filter attribute data collected from all appliances associated with the processor 300.

The methods, systems, and devices discussed above are examples. Various configurations may omit, substitute, or add various procedures or components as appropriate. For instance, in alternative configurations, the methods may be performed in an order different from that described, and that various steps may be added, omitted, or combined. Also, features described with respect to certain configurations may be combined in various other configurations. Different aspects and elements of the configurations may be combined in a similar manner. Also, technology evolves and, thus, many of the elements are examples and do not limit the scope of the disclosure or claims.

Embodiments of the present disclosure, for example, are described above with reference to block diagrams and/or operational illustrations of methods, systems, and computer program products according to embodiments of the present disclosure. The functions/acts noted in the blocks may occur out of the order as shown in any flowchart.

Additionally, or alternatively, not all of the blocks shown in any flowchart need to be performed and/or executed. For example, if a given flowchart has five blocks containing functions/acts, it may be the case that only three of the five blocks are performed and/or executed. In this example, any of the three of the five blocks may be performed and/or executed.

A statement that a value exceeds (or is more than) a first threshold value is equivalent to a statement that the value meets or exceeds a second threshold value that is slightly greater than the first threshold value, e.g., the second threshold value being one value higher than the first threshold value in the resolution of a relevant system. A statement that a value is less than (or is within) a first threshold value is equivalent to a statement that the value is less than or equal to a second threshold value that is slightly lower than the first threshold value, e.g., the second threshold value being one value lower than the first threshold value in the resolution of the relevant system.
